According to KFTC, The CRT Glass producers agreed on fixing prices and reducing output of CRT Glass in the secret meetings which took place in various countries including Korea, Japan, and Singapore at least thirty five times for almost 8 years from March 1999 to January 2007.

In addition, they agreed on fixing prices of CRT Glass by setting the amount of price cut (or increase), allocating market shares by major customers such as Samsung SDI and curtailing production by shutting down CRT Glass production lines. And the CRT Glass manufacturers exchanged confidential business information such as CRT Glass sales, production, market shares to fulfill and monitor the implementation of their agreements.

KFTC's decision is the result of a joint investigation with foreign competition authorities including the European Commission in March 2009.
